ABSTRACT:
A battery charging system is provided for charging a rechargeable batteries and for distinguishing the rechargeable battery from a non-rechargeable battery. The charging system establishes an electromagnetic field proximate the battery. A circuit within the battery enters a resonant condition in response to the electromagnetic field and the resonant condition is sensed by the charging system to switch the charging system from a non-charging mode to a charging mode.
